1. The problem statement, all variables and given/known data

What does the non-negativity of the Coulomb Integral for H2+ suggest about the relative strengths of the attractive electron-proton force and the repulsive proton-proton forces?

2. Relevant equations

N/A

3. The attempt at a solution

I want to say that it means the repulsive proton-proton force is greater since

$$J = \int_{-\infty}^{\infty} \overline{\mathrm{1s}}_A \left(\frac{1}{R} - \frac{1}{r_B}\right)\mathrm{1s}_A \mathrm{d}\mathbf{r}$$

but I'm not sure if I've got the right idea here.
